ABSTRACT
BACKGROUND: Congenital scoliosis (CS) is defined as lateral curvatures of the spine provoked by the anomalous development of the vertebral bodies. It is associated with neuromuscular anomalies, which can be genetic, caused by the compensation of discrepancies in the length of the extremities or intrarachidian anomalies. METHODS: This study was carried out in 2-year-old female, showed alterations in the gait, mainly in the hind limbs, a clumsy gait and a slight claudication in the right hindlimb. To perform the imaging study were: X-Ray projections and Computerized Axial Tomography, neurophysiological evaluation was performed by means somatosensory-evoked potentials of the tibial nerve (SEPTN). RESULTS: The results showed an enlargement of the latencies from the L5 to the cortex, mainly in the left afference, correlated with the imaging studies. CONCLUSIONS: There is no doubt that the concurrent use of different diagnostic tools complements knowledge regarding the physiopathogenesis of these osteopathologies.

BACKGROUND: It has been widely documented that quadrupedal animals rarely display natural spontaneous scoliotic rachis deviations of the spinal column. The objective was to determine spinal deformities developed by geriatric monkeys of the Macaca mulatta species, by radiographical and tomographical studies of the vertebral column correlating morphological changes with altered physiological parameters and electrical neurosensorial conductivity of somatosensory-evoked potentials (SEPs). MATERIALS AND METHODS: A cohort of six geriatric monkeys was used: three non-scoliotic subjects and three monkeys with naturally acquired true scoliosis. RESULTS: Radiographic and tomographic studies depicted a thoracic curvature displaying a left-sided thoracic vertebral rotation. The evaluation of physiological parameters demonstrated significant differences in the respiratory rate, as it was observed for the diastolic blood pressures, which showed a decrease in the monkeys with scoliosis compared with healthy monkeys. Regarding the SEPs studies, the non-parametric test for independent samples Mann-Whitney U test displayed a significant difference observed at the left and right thoracic derivative in P1; while regarding the study of upper limbs, a significant difference was seen at the Erb's point derivative, left afferency in P1, showing in all the derivatives an increase in latency in monkeys with scoliosis versus monkeys in the control group. CONCLUSIONS: This study has demonstrated that quadrupedal animals can develop true scoliosis showing an analogous way to that occurring in humans.

In subclavian steal phenomenon (SSP), the subclavian artery develops a stenoocclusive disease proximal to the origin of the vertebral artery, leading to pronounced hemodynamic changes such as arterial flow reversal. Although SSP is a common echographic finding in humans, the phenomenon occurs only rarely in animals; consequently its physiologic features have not been reported previously. Here we describe the clinical and morphologic features of a spontaneous left SSP that was an incidental finding in an 18-y-old female rhesus macaque (Macaca mulatta). Our findings were documented through high-quality imaging studies obtained by using a computerized 3D tomography apparatus and clinical assessment of systolic and diastolic blood pressures.

Degenerative spinal disease is a leading cause of chronic disability both in humans and animals. Although widely seen as a normal occurrence of aging, degenerative spinal disease can be caused by various genetic, iatrogenic, inflammatory, and congenital factors. The objective of this study was to characterize the degenerative spine-related diseases and the age at onset in a random subpopulation of 20 captive rhesus monkeys (Macaca mulatta; male, 13; female, 7; age: range, 4 to 27 y; median, 18.5 y). Spinal radiographic evaluation (left lateral, right lateral, and ventrodorsal views) of the spinal column (C1 to S1) was performed, and spinal degenerative disease was scored. The incidence of osteopathology was higher in the 14- to 18-y-old group, but incidence did not differ according to sex. In the studied population, degenerative changes were present in monkeys as young as 9 y of age.

Se presenta la experiencia obtenida en cinco años en el Servicio de Radiología del Hospital General "Dr. Manuel Gea González" en relación al manejo invasivo de los abscesos abdominales por drenaje percutáneo guiado por ultrasonido. Se trataron 244 pacientes con diferentes colecciones intrabdominales, a quienes se realizó drenaje por esta vía. Se drenaron 197 abscesos hepáticos amibianos, dos abscesos piógenos, dos abscesos micóticos, 10 abscesos residuales postquirúrgicos, tres abscesos perirrenales, 14 quistes renales, ocho quistes hepáticos, dos hematomas perirrenales espontáneos, dos pseudoquistes de páncreas infectados y cuatro hematomas de lecho vesicular. Se obtuvo éxito en el 97.95 por ciento de los enfermos; las complicaciones fueron mínimas

En esta investigación presentamos el manejo, por radiología invasiva, de colecciones perirrenales de diferente etiología por medio de drenaje percutáneo translumbar como método de elección no quirúrgico. Se colocó un catéter guiado por ultrasonido y flujoroscopia a cuatro pacientes, los cuales presentaron mejoría sintomática inmediata del dolor lumbar. En ocasiones no es una solución definitiva para las colecciones perirrenales, pero siempre proporciona un mayor bienestar el paciente

Se presenta el manejo percutáneo translumbar como método de elección urgente en el área renal y perirrenal en pacientes con cólico nefrítico por procesos obstructivos o colecciones perirrenales de diversas causas, en 20 pacientes de ambos sexos, a quienes se colocó un catéter guiado por ultrasonido y control fluoroscópico. Se obtuvieron resultados satisfactorios, ya que al realizar la descomprensión del área renal o perirrenal, el dolor desapareció en forma inmediata mejorando el estado general de cada uno de los pacientes se valoró la permanencia del drenaje como tratamiento definitivo de tipo paliativo o temporal, ya sea como alternativa del tratamiento o para mejorar las condiciones clínicas del paciente, según el tipo de trastorno en cada caso

Se realizó un trabajo descriptivo, retrospectivo y longitudinal del periodo comprendido de febrero de 1990 a febrero de 1995 con el objetivo de analizar la experiencia de nuestro Hospital en relación al drenaje de los abscesos hepáticos. En total, fueron estudiados 160 pacientes de uno u otro sexo, con edades que oscilaron entre cinco y 55 años, a los cuales se les efectuó punción evacuadora del absceso hepático amibiano refractario al tratamiento médico. Se observó mejoría de los síntomas a las 24 horas del procedimiento y fueron dados de alta en un promedio de 7 a 10 días. El seguimiento de control mostró que estaban asintomáticos a los tres, 15, 30, 60 y 90 días. Sólo se presentó caso de fístula a vesícula biliar, la cual fue resuelta quirúrgicamente. La cifra de mortalidad fue del 3.09 por ciento (dos pacientes). La estadística utilizada fue descriptiva
